Plane Props
What is a bigger gas hog, a helicopter or a plane (prop)?
I'm looking at comparably sized machines, of course (eg: 2 seater plane, 2 seater chopper).
Fuel burn is the same regargless of fixed wing or rotorcraft. If you have a rotorcraft, lets say a R-22 powered by a lycoming o-320. That o-320 puts out about 160 hp. Cessna 172 fixed wings are commonly powered by the same engine. The o-320 rated at 160 hp burns around 8 gph at cruise.
The C172 will true out at about 110kts while the R22 will settle at about 85. So price of operating per nautical mile based on fuel alone... The rotorcraft costs more.
